I've burnt a BDMV from the timeline of VMS 9.0b Platinum (1440x1080, 8 Mbps). However, Cyberlink Power DVD DX does not see the BD (no diskette in the optical disc - DVDRWBD CA10N - or its format is wrong). W7 do identify folders on the BD and a file in the Stream subfolder can be played by WMP, but without audio. Can anybody explain why? Thanks ina advance.
